"RS Magazine" (french) where they tested the convertible 997 with PCCB and then the convertible 997 S with standard brakes...... the journalist concluded that he would give up the extra 30 HP to have the PCCB ! The handling seemed to be so much better because of the loss of weight and much less over-steering. So there much improved handling also with these brakes ... I guess the best would be to have both especially if it improves handling .

 

GT Purely Porsche magazine in the UK did a similar test with the coupes and concluded that they'd go for a low spec 997 with PCCB over a standard 997S (both work out a similar price).

 

I have switched from PCCB to steel with my GT2. I cannot feel any difference about how the car handles. However, I can feel a difference in acceleration. PCCB rotors are about 50% lighter.

The oversteer data point is in my opinion not credible.

Porsche claim better handling through the lower unsprung weight. Other "experts" have noticed the difference.

A while back I drove two 996TT's back to back, one had PCCBS (1st generation) the other steel discs. You could feel a difference in the way the car rode bumps and also how quickly it seemed to start changing direction in a corner. I can only presume that since the brakes were the only variable that the difference was down to PCCB's.

The oversteer comment makes no sense. Understeer maybe, but not oversteer.
